Detailed implementation

[0026] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other implementation manners obtained by those of ordinary skill in the art without making creative efforts fall within the scope protected by the present utility model.

[0027] The present utility model provides a semi-automatic snail tail-cutting machine, which includes a chassis and a tail-cutting mechanism disposed inside the chassis. The tail-cutting mechanism includes a base and a driving part, an eccentric transmission part, a shearing part and a guiding part disposed on the base; the shearing part includes a fixed tool holder and a sliding tool holder. The cutting edges of the fixed tool holder and the sliding tool holder are arranged opposite to each other and are in close contact to form a shearing space; a plurality of shearing through-holes are formed on the chassis, and the shearing through-holes are arranged corresponding to the shearing space; the sliding tool holder is in transmission connection with the driving part through the eccentric transmission part. The driving part drives the eccentric transmission part to swing, thereby driving the sliding tool holder to reciprocate along the guiding part.

[0028] Further, the shearing through-holes are arranged at intervals in sequence along the length direction of the shearing space.

[0029] Only need to manually put the snails into the shearing through-holes, drive the eccentric transmission part to swing through the motor, realize the reciprocating movement of the sliding tool holder, cooperate with the fixed tool holder, and complete the shearing of the tails of the snails. The mechanized shearing process can keep the tails of the snails sheared uniformly, improve production efficiency and ensure the quality of the snails.

[0030] The present utility model adopts a semi-automatic design, which not only retains the high efficiency of mechanical automation but also takes into account the flexibility of manual operation.

[0031] As an optional implementation manner, the driving part includes a motor, the eccentric transmission part includes an eccentric wheel and a transmission plate. The transmission shaft of the eccentric wheel is in transmission connection with the output shaft of the motor, the eccentric column of the eccentric wheel is connected to the transmission plate, and the transmission plate is connected to the sliding tool holder.

[0032] Further, the motor adopts a reduction motor in the prior art as the power source.

[0033] When the motor runs, it drives the eccentric wheel to rotate, which in turn drives the eccentric column to drive the transmission plate and the sliding tool rest to swing reciprocally. At the same time, due to the limitation of the guiding part, the swinging motion of the sliding tool rest is converted into a linear reciprocating movement, so that the sliding tool rest moves towards or away from the fixed tool rest.

[0034] As an optional implementation manner, the number of the shearing parts is one group. The transmission plate is sleeved on the eccentric column and is provided with a transmission groove. The sliding tool rest is provided with a transmission protrusion adapted to the transmission groove.

[0035] Furthermore, the transmission protrusion is of a circular plate structure and is adapted to the transmission groove. The transmission protrusion is clamped in the transmission groove and is rotatably connected to the transmission groove.

[0036] When the eccentric wheel rotates, it drives the eccentric column to drive the transmission plate to swing reciprocally. Through the cooperation of the transmission groove and the transmission protrusion, the swinging motion is transmitted to the sliding tool rest, driving the sliding tool rest to reciprocate along a predetermined path of the guiding part, and then realizing the shearing action with the fixed tool rest.

[0037] As an optional implementation manner, the number of the shearing parts is two groups, and they are symmetrically arranged on both sides of the eccentric wheel; both ends of the transmission plate are respectively connected to the two sliding tool rests, and the transmission plate is provided with a sliding groove, and the eccentric column is movably arranged in the sliding groove.

[0038] The two groups of shearing parts are symmetrically arranged on both sides of the eccentric wheel, and the two sliding tool rests are respectively connected to the transmission plate, so that the rotation of the eccentric wheel can drive the two sliding tool rests to move simultaneously, and then drive the two groups of shearing parts to perform shearing actions in sequence, improving the shearing efficiency.

[0039] When the eccentric wheel rotates, the eccentric column moves along the path of the sliding groove, which in turn drives the transmission plate and the sliding tool rest to swing reciprocally. At the same time, due to the limitation of the guiding part, the swinging motion of the sliding tool rest is converted into a linear reciprocating movement, so that one sliding tool rest moves towards the fixed tool rest and the other sliding tool rest moves away from the fixed tool rest. When the eccentric wheel continues to rotate, the positions of the two sliding tool rests will be interchanged, and then an alternating shearing action is realized.

[0040] As an optional implementation manner, the sliding groove extends along a direction perpendicular to the linear slide rail.

[0041] As an optional implementation manner, the fixed tool rest is arranged at the end of the base, and the fixed tool rest and the sliding tool rest extend along a direction parallel to the width of the base.

[0042] With such a setting, the lengths of the cutting edges of the fixed tool rest and the sliding tool rest are extended, so that the shearing space can cover a wider range, and at the same time, the tails of multiple snails are sheared, improving the shearing efficiency.

[0043] As an optional implementation, the guide portion includes a linear slide rail and a slider. The linear slide rail is symmetrically arranged on the base and extends in a length direction parallel to the base. The slider is arranged at the bottom of the sliding tool holder, and the slider slides in cooperation with the linear slide rail.

[0044] The sliding tool holder drives the slider to move back and forth along the linear slide rail. At the same time, it is constrained and guided by the linear slide rail, which limits the freedom of the sliding tool holder so that it can only move along the linear slide rail, thereby ensuring the stability and accuracy of the sliding tool holder during movement.

[0045] As an optional implementation, a discharge port corresponding to the shearing space is provided on the base, a collection port is provided on the side wall of the chassis close to the shearing space, a collection trough is obliquely arranged on the collection port, and the orthographic projection of the discharge port is completely within the receiving range of the collection trough, so that the sheared snail tail can fall into the collection trough and slide out to an external collection device.

[0046] After the shearing is completed, the sheared snail tail falls into the aggregate trough through the discharge port, and slides out along the aggregate trough under the action of gravity to the external collection device for collection and processing.

[0047] As an optional implementation, a movable window is provided on the chassis to facilitate installation, routine maintenance and troubleshooting of the equipment.

[0050] Furthermore, the shearing through holes 11 are arranged in sequence and at intervals along the length direction of the shearing space.

[0051] It is only necessary to manually put the snail into the shearing hole 11, and drive the eccentric transmission part to swing through the motor 3 to realize the reciprocating movement of the sliding knife holder 7, and cooperate with the fixed knife holder 6 to complete the shearing of the tail of the snail. The mechanized shearing process can keep the shearing of the tail of the snail consistent, improve production efficiency, and ensure the quality of the snail.

[0052] The utility model adopts a semi-automatic design, which not only retains the high efficiency of mechanical automation but also takes into account the flexibility of manual operation.

[0053] As an alternative embodiment, the driving part includes a motor 3, the eccentric transmission part includes an eccentric wheel 4 and a transmission plate 5. The transmission shaft of the eccentric wheel 4 is in transmission connection with the output shaft of the motor 3. The eccentric column 41 of the eccentric wheel 4 is connected to the transmission plate 5, and the transmission plate 5 is connected to the sliding tool rest 7.

[0054] Furthermore, the motor 3 adopts a reduction motor 3 in the prior art as the power source.

[0055] When the motor 3 operates, it drives the eccentric wheel 4 to rotate, and then drives the eccentric column 41 to drive the transmission plate 5 and the sliding tool rest 7 to swing reciprocally. At the same time, due to the limitation of the guiding part, the swinging motion of the sliding tool rest 7 is converted into a linear reciprocating movement, so that the sliding tool rest 7 moves towards or away from the fixed tool rest 6.

[0056] As an alternative embodiment, the number of the shearing parts is one group. The transmission plate 5 is sleeved and clamped on the eccentric column 41 and is provided with a transmission groove 51. The sliding tool rest 7 is provided with a transmission protrusion 71 adapted to the transmission groove 51.

[0057] Furthermore, the transmission protrusion 71 is of a circular plate structure and is adapted to the transmission groove 51. The transmission protrusion 71 is clamped in the transmission groove 51 and is rotatably connected to the transmission groove 51.

[0058] When the eccentric wheel 4 rotates, it drives the eccentric column 41 to drive the transmission plate 5 to swing reciprocally. Through the cooperation of the transmission groove 51 and the transmission protrusion 71, the swinging motion is transmitted to the sliding tool rest 7, driving the sliding tool rest 7 to reciprocally move along the predetermined path of the guiding part, and then realizing the shearing action with the fixed tool rest 6.

[0059] As an alternative embodiment, the fixed tool rest 6 is arranged at the end of the base 2, and the fixed tool rest 6 and the sliding tool rest 7 extend along the width direction parallel to the base 2.

[0060] With such a setting, the lengths of the cutting edges of the fixed tool rest 6 and the sliding tool rest 7 are extended, so that the shearing space can cover a wider range, and at the same time, the tails of multiple snails are sheared, improving the shearing efficiency.

[0061] As an alternative embodiment, the guiding part includes a linear slide rail 8 and a slider 9. The linear slide rails 9 are symmetrically arranged on the base 2 and extend along the length direction parallel to the base 2. The slider 9 is arranged at the bottom of the sliding tool rest 7, and the slider 9 is slidably matched with the linear slide rail 9.

[0062] The sliding tool rest 7 drives the slider 9 to reciprocate along the linear slide rail 8. At the same time, restricted and guided by the linear slide rail 8, the degree of freedom of the sliding tool rest 7 is limited, enabling it to move only along the linear slide rail 8, ensuring the stability and accuracy of the sliding tool rest 7 during movement.

[0063] As an alternative embodiment, a discharge port 21 corresponding to the shearing space is provided on the base 2, and a collecting port 12 is provided on the side wall of the chassis 1 close to the shearing space. An inclined collecting groove 13 is provided on the collecting port 12, and the orthographic projection of the discharge port 21 is completely within the receiving range of the collecting groove 13, so that the cut-off tails of the snails can fall into the collecting groove 13 and slide out into an external collecting device.

[0064] After shearing is completed, the cut-off tails of the snails fall into the collecting groove 13 through the discharge port 21 and then slide out along the collecting groove 13 under the action of gravity to be collected and processed by an external collecting device.

[0065] As an alternative embodiment, a movable window 14 is provided on the chassis 1, which is convenient for the installation, daily maintenance and fault troubleshooting of the equipment.

[0066] Embodiment 2:

[0068] The two groups of shearing parts are symmetrically arranged on both sides of the eccentric wheel 4, and the two sliding tool rests 7 are respectively connected to the transmission plate 5, so that the rotation of the eccentric wheel 4 can drive the two sliding tool rests 7 to move simultaneously, and then drive the two groups of shearing parts to perform shearing actions in sequence, improving the shearing efficiency.

[0069] When the eccentric wheel 4 rotates, the eccentric column 41 moves along the path of the sliding groove 52, and then drives the transmission plate 5 and the sliding tool rest 7 to swing reciprocally. At the same time, due to the limitation of the guiding part, the swinging movement of the sliding tool rest 7 is converted into a linear reciprocating movement, so that one sliding tool rest 7 moves towards the fixed tool rest 6, and the other sliding tool rest 7 moves away from the fixed tool rest 6. When the eccentric wheel 4 continues to rotate, the positions of the two sliding tool rests 7 will be interchanged, and then the shearing actions are performed alternately.

[0070] As an alternative embodiment, the sliding groove 52 extends along a direction perpendicular to the linear slide rail 9.
